The invention is to an optionally piloted aircraft that can takeoff and land conventionally or vertically, and can convert between the two. The aircraft is immune to one or more engine failures during vertical flight through multiple engines and the use of a virtual nozzle. Aerodynamic controls are similarly redundant. Hovering flight is enabled with a novel stabilization system. Long range efficient cruise is achieved by turning off some engines in flight and sealing them into an aerodynamic fairing to achieve low drag. The resulting aircraft is capable of CTOL and VTOL, and is capable of converting between the two modes while in the air or on the ground. The aircraft can also be easily taxied on the ground in the conventional manner. Automatic controls considerably reduce the amount of training a pilot needs to fly and land the aircraft in either VTOL or CTOL mode.

1. A tail-sitting, vertical take-off aircraft, comprising: a main fuselage having a front section at a nose of the aircraft, a tail section at the tail of the aircraft, and a center of gravity at a first position along said fuselage between said nose and said tail;four canards mounted to said fusela
1. A tail-sitting, vertical take-off aircraft, comprising: a main fuselage having a front section at a nose of the aircraft, a tail section at the tail of the aircraft, and a center of gravity at a first position along said fuselage between said nose and said tail;four canards mounted to said fuselage, said four canards mounted to said fuselage forward of said fuselage center of gravity;two tail planes mounted in said tail section of said fuselage;and an engine mounted on each canard, each said engine including an inlet and an outlet. 2. The aircraft according to claim 1, wherein the engine mounted on each canard is selected from the group of a jet, propeller, turbofan, turboprop, or electric engine. 3. The aircraft according to claim 1, wherein the engine mounted on each canard is mounted at an end of each canard remote from the fuselage of the aircraft. 4. The aircraft according to claim 1, wherein the engine mounted on each canard has a moveable nozzle for directing a portion of the thrust of the respective engine selectively in at an angle away from the engine, wherein said angle is in the range of 10-35 degrees. 5. The aircraft according to claim 4, wherein the engine mounted on each canard has a moveable paddle downstream of the nozzle for directing a portion of the thrust of the respective engine selectively in at an angle away from the engine. 6. The aircraft according to claim 1, wherein each canard has at least two engines mounted on the canard. 7. The aircraft according to claim 1, wherein at least one engine mounted to a canard includes an inlet and a forward door moveable between a first position for sealing the inlet to said engine from the air around said engine to prevent air from entering the engine during flight, and a second position for unsealing the inlet to allow air to enter the engine during flight. 8. The aircraft according to claim 7, wherein at least one engine mounted on a canard has a pair of moveable paddles downstream of the nozzle for directing a portion of the thrust of the respective engine selectively in at an angle away from the engine, wherein said angle is in the range of 10-35 degrees, and wherein each of the pair of paddles can be rotated into contact with the other of the pair of paddles to seal the outlet of the engine when said forward door is in said first position sealing said engine inlet. 9. The aircraft according to claim 5, wherein at least one of the canard-mounted engines includes an inlet and a forward door moveable between a first position for sealing the inlet to said engine from the air around said engine to prevent air from entering the engine during flight, and a second position for unsealing the inlet to allow air to enter the engine during flight. 10. The aircraft according to claim 1, including a liftstand system for lifting said aircraft from a first, taxiing position with said fuselage substantially parallel to the ground beneath the aircraft and a second, takeoff position with said fuselage raised at least 45 degrees relative to the ground. 11. The aircraft according to claim 10, wherein said liftstand system includes: a tail wheel mounted to said tail section;an elongated lift stand connecting a nose wheel to said aircraft;a nose wheel connected to said liftstand for contacting the ground;a motor for raising rotating said liftstand to move said from said taxiing position to said takeoff position about said nose wheel;wherein when said aircraft is in said takeoff position, said tail planes contact the ground to support said tail planes on the ground to form a tail sitting aircraft, andwherein said tail planes are hinged relative to said fuselage to absorb shock. 12. The aircraft according to claim 1, further comprising: a rotating pilot seat comprising a seat having a back cushion mounted to a back plate and a seating pad mounted to a seat plate at a first angle;a seat frame for selectively fixing said seat relative to said fuselage;a seat rotator system for rotating said seat relative to said fuselage while maintaining the angle of said back plate relative to said seat plate at the first angle. 13. The aircraft according to claim 1, wherein at least one tail plane is connected to the fuselage by a spring damper strut to absorb shock during landing. 14. The aircraft according to claim 5, further comprising: each canard mounted engine having a first selectively moveable exhaust control surface for controlling the yaw of the aircraft by directing a portion of the exhaust outwardly from a centerline of the engine; andeach canard mounted engine having a second selectively moveable exhaust control surface for controlling the pitch of the aircraft by directing a portion of the exhaust outwardly from a centerline of the engine.
